Just needed a good place to rant. So a parent donates a 20g fish tank to her childs room, because her sons love the fish tank in the preschool room and at home. Buys it brand new, gets filter heater, at first I am impressed has everything you would need when it comes to setting up a new tank, until.......mind you she was just doing what she thought best, and I was in my own room so could not intervene. Fills tank with everything, from what I can tell she did not rinse anything but am not sure. Fills water de-chlorinates, and some sort of bottled starter right after. Probably didn't work because the de-clorinator was API said wait 15 min before adding in any bacteria starter. Stocks it with 5 mixed colored goldfish to cycle the tank, I walked into her picking the bag off the counter and dumping water and all in the tank. Next day, curious I go in see how they are doing cant resist. I only got a peak the night before Find 5 guppies 2 of the large growing plecos 6 neon tetras 6 skirt tetras and a frog on top on the 5 goldies She went to the store when they got a shipment in and all the fish were a dollar accept the frog he was 3 dollars but he was cute. Granted she is a parent and a customer so I am just like ...oh really. That is a interesting way to stock a tank. Not sure really what else to say Day 3: 3 dead goldfish. And a dead neon, I removed them as the teacher of that room was on vacation. Did water change, added TSS that the preschool room still had after the wait period. Trying to do my best. We were closed for 4th of july weekend Come back three more dead goldfish (think they were feeders) and a skirt tetra, sigh test water find out ammonia is way high go figure dead fish in tank for three days tanks not cycled either. 4pp. Do a immediate water change regardless of TSS since it was so high to bring it back to safe levels, tell them they need to get more TSS or allow time for me or teacher to do daily changes. Talk to them about the fish. There response We are going to stop using tap water and used purified? water like the gm told us to she owns fish tanks. So no more using tap water till then. (Ie no water changes) no tss either less I buy it my self. not surprising the tank is down to two skit tetras 4 neons 3 guppy the 2 plecos and the frog. Not sure what they mean by purified water fish probably be dead soon. Still.....try to guide them and they don't listen or attempt to find information on there own it is just frustrating. Maybe I can sneak a few out and put them in my tank at home.
